作者以鬼伞为材料,用遗传学方法,分离了AB=的二倍体单该和具有亲和性的单倍体单该,使之杂交,得三倍性子实体(2n+n)。这种子实体的全部担孢子形成不良,在光学镜下对其减数分裂过程与正常二倍体进行比较观察,结果如下:从合子核融合开始,到减数分裂Ⅰ前期,染色体的结合过程,三倍体与二倍体无大差异。三倍体的染 The authors use the Coprinus as the material, using the genetic method, isolated AB = diploid single and the haploid with the affinity of the single, make it hybrid, triploid fruiting body (2n + n). The whole basidiospore of this fruiting body was badly formed, and its meiosis process was compared with that of normal diploid under optical microscope. The results were as follows: From the beginning of the zygote nucleus fusion to the prophase of meiosisⅠ, the chromosome binding process, Triploid and diploid no big difference. Triploid of the dye
